Marigold – cultivation aspects and pigment extractionperumal king
The information about marigold cultivation, varietal description, pests and disease management and pigment extraction procedure is explained in detail.
Radish is a popular vegetable in both tropical as well as temperate regions. It is cultivated under glass house conditions for early market, but large scale cultivation in the field is more I common. Being a quick growing crop it can be easily planted as a companion crop or intercrop between the rows of the other vegetables. It can also be planted on ridges, separating one plot from another. It is cultivated all over India, especially near the city markets. Radish originated probably in China. In India, it seems to have been cultivated from ancient times. It was popular among the ancient Egyptians and Greeks. The botanical name of radish is Raphanus sativus. The enlarged edible roots are fusiform and differ in colour from white to red.
Litchi (Litchi chinensis) is a delicious juicy fruit of excellent quality. Botanically it
belongs to Sapindaceae family. Litchi fruit is famous for its attractive red colour, excellent
quality characteristics and pleasant flavor.
Soil and climate:
Litchi is a sub-tropical fruit and thrives best under moist sub-tropical climate. It usually
prefers low elevation and can be grown up to an altitude of 800 m. (m.s.l.). Deep, well drained
loamy soil, rich in organic matter and having pH in the range of 5.0 to 7.0 is ideal for the crop.
Litchi cannot tolerate frost during winter and dry heat in summer. The temperature should not
go beyond 40.5 0C in summer and below freezing point in winter. Prolonged rain may be harmful
especially at the time of flowering, when it interferes with pollination.
Cultivars:
A large number of varieties are grown in different parts of India. Bambia, Ellaichi,
Muzaffarpur, Seedless early, Seedless late, Shahi, Pottee, Rose scented, China, Purbi, and Kasab
are the suitable varieties for NE region.
Propagation:
Air layering is the most common method of propagation. Select healthy and vigorous one
year old twigs and remove 2 cm wide ring of bark just below a bud. IBA or Rooton may be
applied at cut portion for early and more rooting. The cut is surrounded by mud ball containing
moss (2 parts damp moss and 1 part of soil from the basin of old litchi tree) and wrapped with
polythene sheet. Both ends are tied with fine rope to make it air tight. When sufficient roots are
formed in about 2 months, the branch is cut below the soil or sphagnum moss and potted in a
nursery. July to October is the most appropriate time. About 6 months old air-layered plants
should be planted in permanent field in monsoon.
Planting:
Pits of 90 x 90 x 90 cm in dimension are dug at the spacing of 8 – 10 m apart in square
system. Pits are filled with topsoil mixed with about 40 kg decomposed compost, 2 kg
neem/karanj cake, 1 kg bone meal/single super phosphate and 200-300 g muriate of potash.
Incorporation of about 2 baskets of soil from the root zone of old lychee trees encourages the
mycorrhiza growth. Planting is done during June to July. At the time of planting a hole the size
of ball of earth is made in the centre of the pit at the marked point where the plant is fixed and
the soil is pressed to remove air. Watering is done immediately after planting for proper
establishment. Subsequently the plant is regularly irrigated till it is properly established.
Training and pruning:
Training of the plant in the initial stage is essential to provide the required framework.
Unwanted branches should be pruned to provide definite shape and to promote growth of the
trunk and crown of the tree. Three to four branches 60-75 cm from ground opposite to each other
are allowed to form the proper frame of the tree. Further, crowded and crisscross branches are removed to facilitate better growth.

8. ECOLOGICAL REQUIREMENT
Litchi is subtropical fruit
Bearing tree is much affected by HOT
WIND causing fruit cracking
Alluvial soil with good drainage is
suitable for litchi orchard.
It can grow in wide range of soils
from light sandy to heavy clay.
SOIL
The temperature should not
go beyond 40.5 0C in summer
and below freezing point in
winter

9. VARIETIES
EARLY-dehradoon(fruit have an attractive colour),
Early badam (seedless variety) ,
muzzafarpur, shahi
MEDIUM- rose santed, Mclean
LATE- seedless late(late bedana), calcttia, china
10. PROPAGATION
Through Seed
Through vegetative.
Litchi seed loses its viability with in 4-5days of its extraction from the fruit.
The trees raised from seeds are very slow to come into bearing and may
take 10-12 years to come to bearing.
In vegetative propagation technique, litchi can be propagated through
cutting, budding, layering and grafting.
AIR LAYERING(in the month June-July) is the Commercial method of
propagation.

12. Details Usual Practice
Planting Time • August – September
• Planting may be done in spring and early summer if irrigation facility is available
Planting Distance • 10×8m.
• Average no. of plants- 200 per ha.
Size of pits • 1x1x1 m (pits are dug a few weeks prior to planting)
Filling of pits • Pits are left undisturbed initially for a period of 15-20 days.
• Filled with top soil mixed with manures and fertilizers @ 20-25 kg FYM, 2 kg
bone meal and 300 g muriate of potash per pit.
Planting • Square system of planting is usually followed.
• A small hole is made at the centre of the pit and the desired material is planted.
Water is applied immediately after planting

14. Methods- Basin or ring system of irrigation is recommended.
Two irrigations at an interval of 45 – 60 days during winter
is required for bearing litchi trees.
The trees are irrigated from flowering onwards until the
completion of the post-harvest flush.
However, the growers normally irrigate the tree at 7 to 10 days
interval from panicle emergence to fruit harvest or until the post-
harvest flush appears
Irrigation
15. Intercultural Operations
Mulching- The farmyard
manure, compost or straw may
be used for soil mulching.
Cutting down of tall growing
weeds in the orchard and
spreading them over the soil is
another method of mulching
the soil.
Training & Pruning- After
planting, a certain amount of
pruning is often necessary to
give proper shape to the litchi
plant
Once the desired shape is
achieved, no pruning is usually
necessary, except the removal
of dead or diseased branches
16. Weed control
Weeds compete with the trees for water and nutrients.
Mulches used include wheat, barley or rice straw, hay,
sorghum stubble and similar materials.
Reduce costs by growing mulch material between the rows
for later slashing.
18. Harvesting
Depending on the tree age there are four
growth phases in litchi plants
young non-bearing stage (1-3 years),
young bearing stage (6-10 years),
junior adult bearing stage (11-20 years)
senior adult bearing stage (21 years and above).
Harvesting is usually done in May and June.
The fruits are harvested in bunches along with a portion of the branch
and a few leaves.
19. 80-150 kg fruits/tree.
Storage temp:- 0 -1 °c with 80-85% RH.
Storage life:- 3-4 weeks.
Grade used in litchi:-extra class, grade-I, grade-II.
